Saadabad historical and cultural complex is a collection of mansions and palaces that are built in Darband, the northernmost region of Alvand, on a 110-hectare land. The complex has about 180 hectares of forests, springs, aqueducts, orchards, greenhouses and streets. This mansion is bordered by Alborz mountains from the north, Golabodreh from the east, Velenjak from the west and Tajrish from the south. The Jafarabad River flows through the middle of the palace grounds. The average annual temperature of this region is estimated at 12.9 degrees Celsius and it is located at an altitude of 1650 to 1800 meters above sea level. During the first Pahlavi period, the entire Saadabad garden was drunk from the Darband River; But in the second Pahlavi period, due to giving water to the people in the middle of the day and night and not enough water to irrigate the entire complex, twelve old and new aqueducts were used.

Saadabad complex has gone through four historical periods of Qajar, first Pahlavi and second Pahlavi and after the Iranian revolution. Saadabad was built during the Qajar period and was the summer residence of the kings of this dynasty. After the coup d'etat of 1299 and its occupation by the Pahlavi dynasty, several buildings and mansions were built in it, which can accommodate 18 palaces in different dimensions. Each of the buildings was the residence of a member of the Pahlavi dynasty. Mohammad Reza Pahlavi also settled in this place in the 1350s; Which was completed during the early days of his reign. The newest palace in this complex is Leila Pahlavi Palace, which belonged to the youngest daughter of Mohammad Reza Pahlavi.

After the victory of the Revolution of 1957, this complex became a museum, but the current presidential palace is located next to this complex. The Queen Mother Palace, which belongs to the Presidential Palace, has also been used to receive foreign guests.
